ZForce Sway Bar Bushing Upgrade
« on: October 21, 2015, 09:00:09 pm »
ZForce 800 Sway Bar bushing upgrade to Polyurethane

As we 53” Z8 owners are aware, our machines are a bit tippy and unpredictable on hard corners and in power slides. Even myself have had my share of “pucker” moments. From past experiences it is known that the flatter it stays the longer it will stay on all fours. Width is the biggest help but also not allowing the body to roll over as easy or as far to meet that critical point also helps a great deal. For almost 10 years my Brute has had a set of Energy Polyurethane sway bar bushings and that has helped it stay planted on corners and slides like a go-cart on asphalt. With as much slop as the zforce bushings have it’s no wonder that don’t want you to do any broudys, donuts or power slides. They have even set the clutches so it’s harder to do them.. for safety I assume. Well, now that mine wants to do them all the time with a touch of the gas, I though it time she got her own set of bushings.  If it helps the Z8 anything like they did for the Brute, the 20 bucks will be some of the best money ever on it spent.
 
A few measurements and these were the correct ones for the Z8s:

Will need to add a washer to the bolt as these cone with a slot that's a bit wider then the OEs with the hole. And be sure to clean the bar well before installing the new bushing.

One thing I don’t use any more on these is grease. It gets hard and binds over time and the grease track gets blocked. I use weapons-grade graphite. Perfectly smooth for years and no squeaks! The Brutes now have over 4000 miles on hers and they are still as tight as the day they were put on. I think I have cleaned and re-applied the graphite twice in all that time.
So, the same shall be for the Z-8. Can’t wait to get it out on the desert for some HD play.
Here’s a little video I did on this mod.


I would like to also state this modification/upgrade does not eliminate the possibility of a roll-over. It only increases the force required to do so. So don't go out and do donuts on asphalt right afterward thinking you are save...lol

UPDATE 10/28/15:

OK, here a little video of the testing of the new sway bar bushings. Not the best but at least it will give you some idea of how much more flat it stays in corners and the added control on twisty, whoopee trails.


UPDATE 6/7/16:

After running these for a few hundred miles I found that these fit the bar a little tighter then my Energy bushings do on my Brute Force and as such, moved/worked all the graphite out from between the bushing and the bar making it not only hard to rotate but also squeak a little. For now I took ends loose and greased the fittings with my graphite grease in all positions ,then worked it all in so it was smooth and easy again, then reinstalled. Later I may remove and adjust the fit so they aren't quite as tight against the bar. Although you want no play, you also way no binding.

UPDATE 8/10/16

I was hoping these would wear a little quicker but after twice having to relube because of the tightness against the swar bar I decided to "Help" it wear in by running a round file through them enough for them to fit the bar with no play, but no pressure being exerted from the frame after install. This should help keep lube inside and stop the binding as well as the noticeable wear showing on the bar from being too tight.

Graphite?

Yes. Super stuff as long as it doesn't get used under water all the time. This stuff right here:

Probably not for a long time. I've never had one in enough water to wash it out but even if so, I now use a graphite based grease for my a-arms that would probably work real nice for these too...and they are grease-able just like the OEs.

Got two black on order. Thanks a ton.

Also, I gotta re-think the bed screen like your original intake re-route.

It's been raining for days up here so our raods and trails are making a muddy mess. The bed and rear windshield are covered in road spray.

Maybe something with a hood would be better up there. Someone posted a possibility on that thread. Here its dust and a few sprinkles and that cover should be fine for me. I do really like having a filter before the airbox though...then having another quality filter in it. The course foam was fine but the new UniFilter material is so fine it might work too well and become restrictive to soon. I'll let you guys know after testing. At least I know the one that comes with it works OK even without the prefilter. 

By the way, just a FYI to everyone, when I switched-out my "almost new" CFMoto air filter for the twinAir when installing the mushroom filter, I swabbed the inside of that OE filter and found that some dust and grit did pass through it and some was on the flange edge. That means some did get to the engine. That is 100% unacceptable. I highly recommend all you guys get either a TwinAir or the UniFilter unit and the correct oil..and get them on.. right now.

Just as I suspected, the screen let in too much debre. The air box was full of water. On my way back from Houghton Lake, I had no power. Opened the air box and water came pouring out. My UniFilter did a fantastic job of keeping the junk out. Unfortunately I still had to get home from the shop so I drained the air box and replaced it with a TwinAir and the prefilter.

I agree the stock air filter is total garbage. Paper element air filters have no business in off road applications.

Has to be foam filter oil. Unit has theirs... so does TwinAir, I use No Toil. Bell Ray makes the stickiest. They all also use their own cleaners. Get it too.
